Small Intestine Keychain

Small Intestine Keychain

Churned food travels from the stomach into the long, convoluted small intestine.

The first section, the duodenum, is 12" long. The next two sections, the jejunum

and the ileum, are a combined 16 feet long. Millions of finger-like projections

called villi cover the intestinal lining and provide an enormous surface area for

absorbing nutrients, which pass into the bloodstream to feed your body's cells.

Small Intestine mini microbe (3") includes mini-tag and key chain clip.
